Zollant has customized a matching air compressor for the cutting industry, which can meet the demanding requirements of various laser cutting equipment for water, oil, and particles in compressed air. The product adopts five-stage filtration and non-heat regeneration adsorption dryer. Pressure dew points up to -20 ° C ~ 70 ° C.
To explore in the cutting machine industry, the cost of liquid oxygen per barrel is generally about 70-90$. If your machine work 8 hours a day, you can consume this barrel of oxygen in about 4 days. The average cost of oxygen reduction is 19$ per day. If you are interested in reducing the cost of using the air compressor for laser cutting industry, feel free for contacting Zollant.
There are different types of air compressors. They come in different designs and configurations. One of the most common types is the 2-stage screw air compressor.
In this guide, we are going to guide you on how to buy a 2-stage screw air compressor in China.
A 2-stage screw air compressor is an air compressor that compresses 2 stages.
2-stage models are more complicated than a single stage. 2-stages compress the compressed air in 2 steps (hence 2 stages), giving you cooler and better-compressed air, allowing your tools to run smoothly.
The 2-stage air compressor also has two oil reservoirs, two lubrication systems, and two transmission systems.
2-stages screw air compressors are typically more complex than single-stage models. 2-stage air compressor’s features are explained below:
2-Stage air compressor works for 2 steps to pump up the tank. 2-stages compressors work by first drawing air into the 2nd stage.
2nd stage pressurizes it and sends compressed air to 3rd oil separator (there is 2 oil reservoir in 2-stage).
An oil reservoir keeps the lubrication system running (2 lubrication systems).
Air will be sent out of the second stage once there is no more pressure to compress, this makes sure you get only clean and dry compressed air.
Two are the most efficient of all air compressors. A 2-Stage air compressor is not different from a single stage in how it works, but 2-stages are more complicated to make it more efficient and last longer.
The two are typically bigger than single stages because 2-stage air compressors have 2 cylinders.
Two stages are more powerful than a single stage at the same capacity. A 2-stage air compressor is typically used in workshops, factories, etc.
Let’s look at the main parts and functions of a typical 2-stage screw air compressor.
The 2-stage air compressor has 2 air reservoirs (separated). This separates the clean compressed air from the oil reservoir that’s why you get only pure & dry compressed air.
The heads are connected to 2 cylinders. Cylinders move up & down when compressing air 2-stages, making it more efficient in compression.
The 2-stage compressor head is typically cone-shaped with 2 stages in it. The 2-stage compressor head has 2 exhaust valves on top of the cylinder to let out hot compressed air 2-stage models.
2 exhaust valves help 2 stages compress the air more efficiently throughout the stages.
The pistons rods connect pistons to the compressor head. Piston rods are connected to gaskets inside 2 cylinders, where compressed air will be pushed in. 2-stages have 2 pistons that work 2 times faster than a single stage 2 2-stages.
Oil reservoirs are connected to 2 lubrication systems to oil up the rotating components. Oil reservoir keeps 2-stage compressor from wearing out 4 2-stages.
2-stage air compressors have 2 lubrication systems so 2-stages can compress air effectively. 2 lubrication system keeps 2 stages cooler and last longer.
Transmission is typically a belt system, where transmission is one of the most complicated parts of the system. The compressor may have 2 or 4 transmission assemblies. 2 2-stages are more complicated to produce, so typically 2 stages are expensive than single-stage models at the same capacity 2-stages.
-High efficiency: 2 2-stages have 2 cylinders, 2 pistons moving 2 times faster than a single-stage compressor at the same capacity 2 2-stage models. Heat degradation in 2-stages is typically lower in 2-stage air compressors.
-Better compression:
2-stage compressors compress air into smaller molecules that can put more pressure. 2 2-stage air compressor is typically used in workshops, factories, etc.
-Longer life:
2-stage air compressors have a better lubrication system and more efficient compression.
2-stage air compressors typically cost more than single-stage air compressors. This means that you will have to pay more if you opt for the 2-stage air compressor than for the single-stage.
However, it is imperative to note that the higher price comes with extra values. You will enjoy a plethora of features that come with this air compressor.
Here are some key factors that you should consider when buying a 2-stage screw air compressor:
-Size: How big is your workshop? If you need to use compressed air tools like nail guns, this would affect the size of your 2-stage compressor.
-Capacity: How much volume do you need to fill up per minute? This will determine the capacity of your 2-stage compressor.
-Motor power: What voltage and PSI power do you need? This will determine the voltage and PSI of your 2-stage compressor.
-Noise: The noise level is important for those working in workshops. If you’re not using compressed air tools, then this factor would be less crucial.
These two air compressors differ in some ways. First, a 2-stage air compressor has 2 cylinders, whereas a single-stage air compressor has one.
Second, their valves and pistons work differently. 2-stages have two valves on top of the cylinder to let out hot compressed air 2 times faster than a single stage at the same capacity 2 stages.
Single stages may have either piston or diaphragm valves that handle only one way while these two types of valves in 2-stages do both compression and decompression of air efficiently.
These two types of valves put less weight on each other so they can move more freely without wear and tear for a longer life span. Fewer moving parts mean lower noise levels during operation for people working in workshops.
I hope that you have gained valuable information about 2-stage air compressors. You should now be in a position to buy one. All you need is to finde reliable 2-stage air compressors manufactirers in China and buy one. You will get all the other information, including the price of 2-stage air compressors.
